WAC 2021 Runner-Up

AeroPress by Maru Mallee

Maru Mallee's runner-up entry at the 2021 World AeroPress Championship uses an inverted immersion, forceful stirring, and a Rao-style finishing swirl. Room-temperature bypass cools and opens the final cup while setting its strength.

Notes

Use one rinsed paper filter and stir firmly enough to wet every particle without scraping the filter. After pressing, add 36g of room-temperature water and swirl for about 1 min; this integrates the bypass, lowers serving temperature, and lets sweetness become easier to assess.
